monster-arcs from flyback

[MrStemkilla]

how meany amps?

[johny260]

but can you make it sing?

[Volta500]

That's a ZVS alright! Nice arcs. Hope the flyback will survive.

[paintballgundown8]

your neighbors wonder why their lights always dim

[a380rockerfan]

Did your IGBTs need cooling? If so, what kind kind of heatsink or kind of cooling did you use?

[jmartis2]

@a380rockerfan The MOSFETs needed small sized heatsinks like those from pc psu

[ExplosiveAnyThing]

@jmartis2 Can i use ir21531 (i probably can) what mosfet driver you use? .. Also is this driver stable???

[ExplosiveAnyThing]

@jmartis2 You are using the ir2151? Also the primary is AC or (pulsed)DC?

[jmartis2]

@ExplosiveAnyThing I was using the IR2153. Supply for the inverter was smoothed DC, the primary gets high frequency AC waveform from the half-bridge.

[ExplosiveAnyThing]

@jmartis2 Thanks for the reply!! Is this circuit similar with that you have on your website? The half bridge driver ?

[olmosleoso]

segui jugando que te moriras asi XD

[STEVGOT11]

better then a mot or a nst

[a380rockerfan]

Nice! So that's half-bridge with rectified mains running through that flyback? How can those older AC flybacks stand that much voltage and current?

[jmartis2]

@a380rockerfan Yes it is.This one was tougher than the others, maybe because the secondary was potted in a thick layer of epoxy.

[a380rockerfan]

@jmartis2 Is there any thing in your circuit that makes it distinct from others because the arcs are so big? I'm planning on making a half-bridge circuit to drive an inverter transformer from a microwave or a flyback and I know that there are no fixed or official half-bridge schematics out there, so is there one of your circuit that I can refer to? I've got a post on 4hv.org, "Microwave Oven Inverters - How to run them?" fro more info my project. Many regards, Jozef.

[jmartis2]

@a380rockerfan The schematic is similar to this danyk.wz.cz / igbt_2 . html (remove spaces) but any other half-bridge circuit, such as GDT driven, will work as well. The arcs are probably result of a good combination of transformer/primary/frequency.

[ExplosiveAnyThing]

@jmartis2 does the mosfets get hot??? I mean is effiecient??

[hbycoily]

hi , all very good, flame like arcs. do you have the driver schematics & can you sne dthem to me please

[mathscirocks]

how is that a flyback? i heard that 60 Hz buzzing sound when it arced. the sound a flyback makes is supersonic

[jmartis2]

@mathscirocks Its the mains ripple on the filter capacitor after the rectifier.

[ExplosiveAnyThing]

@jmartis2 how big this flyback is????? Is like standard size beacause it seems really big!!!

[jmartis2]

@ExplosiveAnyThing I think its pretty standard size, like the bigger ones from from b/w TVs.

[snareNL]

@mathscirocks hehe sorry but it just sounded funny =p sound thats faster then the speed of sound =p

[paulma8]

is it possible for the flyback to explode or will it only burn out?

[powermaks]

how many volts and amps go into that?

[drainocleanser]

now put your dick in that ark

only then will you enter into manhood

[achemachew]

I used to play with Flyback Transformers. I like high voltage. I would grab the insulated wire by hand and get it to arc to ground.

[Jakobus999]

I dare you to eat it! XD

[Steelthebest]

Crazy bitch

[sn0wD]

just a question is it the camera (because of magnetic field) or are ur lamps in the room going off/on when u touch something?

[powermaks]

@sn0wD no, fust the bright ark is saturating the camera (the automatic brightness) the can will dim the whole video to show how bright the sick ark is.

[GeeksRus95]

HOW MANY AMPS ARE YOU DRAWING?!

[jmartis2]

@GeeksRus95 I think this drew around 500 watts from the 230 volt line, so something over 2 amps.

[GeeksRus95]

@jmartis2 It looks like a alot pore than that and I meant the peak power drops not the RMS amount of power it's drawing. o~0

[brandonhughes7]

@jmartis2 so it could kill you then right

[ConnorXV]

I'd say as a propulsion force it is poor but on the other hand it has the ability to run for years on end non stop giving an unimaginable advantage over chemicals for ultra speed capability in space, (a plasma propulsion drive) I'm not sure about electromagnetic stuff so no answer, I am sure you can find a plasma electromagnetic nerd here somewhere though : p

[Masamuneblade7]

@ConnorXV Yeah, I found you can bend plasma into different shapes with magnets and electromagnets. I am trying to build my own flyback plasma generator so that I can take advantage of it... I want to see if I can make triangle shaped magnets, or circular magnets turn the plasma arc into a blade like shape

[FREEGARYMCKINNON]

is this plasma gas?

[ConnorXV]

@FREEGARYMCKINNON its just plasma, the state after gas. the bright glow you see is the gas being repeatedly ionised by the massive charge in the circuit, this then causes breakdown of the air (oxygen, nitrogen and other gases lose all their electrons) as the electrons go back to their elements you get a flash of light given off coloured according to the gas primarily in the air, nitrogen gives blue hence the colour.

[FREEGARYMCKINNON]

@ConnorXV thanks man , thats one of the best definitions ive heard : )

plazmahh ! how good is plasma as a propulsion force ? is plasma electromagnetic ?

[a380rockerfan]

hi there! I'm so jealous of circuit! i just have to make one sometime... anyway, could you please send me a PM of the schematic or link of the circuit because I can't find a schematic for this online. thanks, jozef.

[godforge2003]

what a messy place...this fool will surely start a fire. sheesh.

[ubuntupokemoninc]

what is the schematic, just a zvs?

[jmartis2]

@ubuntupokemoninc A mosfet half-bridge.

[z0tx]

What wire size do you use?

[XTYNoLuck]

crazy motha...fa'.....

[Jochen754]

O_O  :O

[TeravoltOrg]

What MOSFETS are you using?

[juniortore1]

so, at what moment did your flyback burst out in flames and smoke? What is the driver pls

[jmartis2]

@juniortore1 the flyback died on my vacuum tube driver. The driver here was a MOSFET half-bridge running from 320V dc and at some 40kHz.

[Sheri451]

Science was always my favorite subject in school.

[00011theman]

monster electric bill much?

[jmartis2]

@00011theman not really. The input power was below 500W and I didn't run it for hours ...

[00011theman]

@jmartis2 ok...

[Kardenum]

Fuck my eyes, the arc's worth it lol

[storyb23]

Wow, impressive. indeed. I wonder if you could turn that into a big plasma speaker

[MegaMaxyKing]

whats the input? how much amps and voltage?

I am going build a halfbridge driver with the same Ic like u

you are the flyback king on youtube =)

[MUZHIKGTA]

Видео оправдывает свое название, аж не верится что это один строчник с одной хв катушкой))) МОЛОДЕЦ!!!

[natna25]

good job imagine puting your hand in there ouch!

[zker666]

Wait, do you have the schematic for this? If so, is it your own design? because you are known for ur flybacks! also, how much current draw?

[jmartis2]

@zker666 This was driven from a standard half-bridge circuit, I think the power draw was something like 500W peak

[zker666]

@jmartis2 Is the half-bridge similar to the mazzilli(ZVS)? i ask because they both use dual FET's

[jmartis2]

@zker666 not really. The zvs driver uses a parallel resonant current fed topology, but the half-bridge is a voltage fed inverter. Really the only difference is that they both use two MOSFETs :-D

[Desaster6]

very nice Flyback LOL, vor a flyback its the strongest arc i ever seen....

but my resonant Mot works ^^

[jmartis2]

@mysticchip no, I have the instructions for most of my projects just "in my head". I usually make schematics just for final versions of my projects.

This driver was with the IR2153 chip, you can find typical connection diagram in the datasheet, but I don't recommend that chip as it tends to explode the transistors as the power is increased.

[jmartis2]

@mysticchip I drove it with a simple half-bridge driver. The frequency was around 40 kHz

[kartkid100]

holy shit, thats from a flyback? you mean like out of a tv?

[jmartis2]

@kartkid100 yeah :D

[death7metal7girl7]

U rock ;)

[kittools]

can you please send me the wiring diagramm from the driver?

[NeitSotm]

Wew, that's pretty big.

[diegoribadacunha]

"You think thats a taser?" (taking out your flyback transformer) XD

[bonecrime]

How come that the flyback don't overheat with that amount of power?

[weeardguy]

@ bonecrime: flyback-quality differs widely: some types die immediately when overpowered, the other can get smoking hot before burning the secondary

[arckon09]

wicked

[08Kutt]

AWESOME!!!

[KileSimons]

mmmm, plasmalicious

[Aqlor]

I don't know a thing about HV, but why is this arc more like a flame than others that are more like a string?

[jmartis2]

It's because this arc has more current :)

[Aqlor]

oh! its seems one enormous difference then xD. niice

[drogirant8]

OMFG

[zker666]

is this a high-amp circuit or just a high volt low amp circuit? just wondering because they look kind of like a resonant MOT arc if you ask me.

[jmartis2]

It is high voltage of course, the amperage is quite a lot lower than resonant MOT arc but I guess it could have been in the 50-100mA range

[zker666]

oh ok because i have a flyback driver circuit going in at about 12 volts at around 2.5 amps and my arcs are NOTHING like that. my arcs are only about 2 inch corona wind and only about 1.5 inch draw arc

[zker666]

yes, but what is the input power you are running at? a high amp circuit maybe 5 amps at 12 volts or more like 40 volts at maybe .5 amps? just wondering because this one is awesome!

[jmartis2]

this one was powered from rectified mains (320 volts dc) and probably drew something like 500 watts at maximum arc length.

[zker666]

fullwave or halfwave rectified mains?

[jmartis2]

Fullwave

[dannybeckett01]

whats your input voltage?

[jmartis2]

Its rectified mains, ca. 330 volts dc

[Shockszzbyyous]

but why is it tough?

[jmartis2]

Probably it was built well and potted in a thick layer of epoxy.

But this transformer is now fried, it fell a victim of tuning the capacitor in my vacuum tube flyback driver :(

[Shockszzbyyous]

ah :)

[SmashCOBamberg]

wow, that's a lot of power! Does the flyback heat up btw?

[anorwood84]

doubt it, but i'm sure the driver was about to fry

[darkthero]

Wow whats yur input voltage and amps?

[nattsurfaren]

I think the fumes from the arc is not healthy.

[gbnnn]

Thats possible. :-)

[plavins1]

hey i have a question!!!! can i use it directly from tv???like take of the anode wire from monitor and hook it up to ground of ???will it make sparks if i do that cuz i dont want to sottor the flyback out just jet!!!Lol

[jmartis2]

yes it will make sparks, but they will be kinda small, and your driver circuit will pop quickly if it doesnt pop as soon as you try to draw an arc...

[plavins1]

it means i woud not be able to run jacobs ladder??

[jmartis2]

maybe it would, maybe it would pop :-p

[plavins1]

ok thanx but how can i make a driver for flyback???

[jmartis2]

try to use google.. if you want a lot of power and a relatively simple circuit, google "zvs flyback driver"

[gabi2060]

cool video

[CoolDudeClem]

How may kilo volts is that?

[codemsan]

man i love these arcs! how much more efficient is this than your average dual MOT stack, or resonant circuit would you say? i know it is, but how much? thanks in advance!!

[rtbr828]

Nice video! Could you send me the schematic please?

[lbochtler]

Me too!

[Blodslav]

Holy smokes what sorta driver is that!? I want one! Man thats gotta bee around 100kv...

[jmartis2]

It was a half-brige. Bridges have enough power to smoke just any flyback, if you use any decent MOSFETs (e.g. IRFP460 or similar)

[kalebman5000]

Wish i had more b/w tv parts.... :(

[gbnnn]

Were the lights dimming?

[jmartis2]

no, just the camera adjusting exposure.

[gbnnn]

Ah! I see.

[morganhv]

where did you get the flyback?

[jmartis2]

from a B/W tv

[dearlydeceived]

nice

[juniortore]

which half-bridge inverter is it theres like 20

[jmartis2]

To be specific, it was a MOSFET half-bridge running from rectified mains (330V DC)

[juniortore]

thank you

[codex653]

you ran this from rectified mains? how did you do that? would this work on a flyback with homemade secondary?? it should shouldn't it? what was your set up on this?

[jmartis2]

Ok, if you want a detailed answer... This particular bridge ran on the IR2153 half-bridge controller, but has since been ditched because it is known to explode the FETs for no reason. (continues below)

[jmartis2]

It is much better to use a pair of gate drive chips, such as the UCC37321/2 or TC4421/2 and a GDT (gate drive transformer).

Yes it would work, if your secondary doesnt burn down :)

[juniortore]

was the transformer hot at the end? it should be

[jmartis2]

I think it was not.

[juniortore]

excellent

[RaikouTch]

You should try making a speaker out of this; with an arc that thick/long it would probably put out some decent bass/loudness.

[Individuality1990]

....do you know how a speaker works?

[bonecrime]

He probably means to modulate the driver with an audio signal, so that the arc plays the music so to speak.

[akkudakkupl]

i dont think so. the bas would cut a lot because the plasma has so low mass. well thats anyway what i think would happen. but this would make great and loud twitter

[juniortore]

ain't that a lot for that size flyback?

[rustflekk]

such a frenzy at the end. hahaha

[voon100]

Beautiful arc. Ever tried to hook it parallel to a high voltage cap? I could imagine you can get some serious bang out of it.

[ShadowCardoso]

WOW!

How did you manage to get such big Acrs as those? :O

Can you give me some schematics or a guide wich I can follow?

I've managed to do the guide on instructables that 'Ravenpulse' Refered but the acrs aren't big enough..

[jmartis2]

I used a half-bridge inverter. This is the toughest of all of my transformers and it still works!

[Ravenpulse]

i read on instructables that if u use a compact fluorescent light's (energy saver light) electronic ballast (not the old clunky ballasts) and connect it to the flyback, that it will be just the right frequency and voltage to drive the flyback. is this true?

[jmartis2]

yes, but the power available is just too small to do anything useful. The power used here is about 100 times higher than you would get from a CFL driver running a flyback.

[phaub]

Power "just too small to do anything useful" is what I would recommend for someone doing this for the first time though.

I wouldn't want putting my hand too close to this one...

[extrasonic]

I have a question.

I want to make a big singing arc, so I want to know from what its length depends of the must ?

-From the driver ?

-Or mostly from the flyback transformer ?

-From both, but it depends of many factors, and also luck ?

You can look at my video, powering my flyback at 12V. The arc is very small. I'm going to make a full bridge schematic this time.

[jmartis2]

You ask what is limit for the arc length? Well, if you have powerful enough driver, what limits the power is really the transformer. But for optimal performance, the driver's topology and frequency, magnetic flux in the core and leakage inductance must be choosed right.

For example, if you use too much turns, the transformer will not reach its full voltage, if you use too high frequency, the core will get hot etc.etc.

[extrasonic]

I'm planing of building a TL494 fullbridge, I hope it's powerful enough. Before I built a simplified version, using only 1 field transistor at the exit. The sound quality was acceptable, but the arc was short. And yesterday I got the transistor and the IC burnt, I don't know how it happened. Very sad.

I also don't have a place where to wind a primary coil, so I have to use the integrated ones. Thanks for the info.

[izidor7]

In that case if the flyback is to week you cannot overload it without distroing it... that is a fact.

Your video is awsome RESPECT for that.

I must say your workplace looks almoust like mine.

Respect man for your good work!

[izidor7]

I know a litle modification you could make on your H-bridge and it would operate at full voltage. It would operate like a full bridge (the input voltage would go on the primary) but would staly like a H-bridge.. So if you are interested ,,, Just tell me.

If you put more power in the flyback it probebly would turn some of that power to a powerful arc. It is easier to hamdle les power but ok!

[jmartis2]

I think it won't handle anymore than that, more voltage and it arcs to the core, more current and the secondary winding gets hot!

[izidor7]

12V and 100A ok. i mean which igbt would handle that,,, that would be an cool induction heater. yyou would just need to put an work coil instaid of a flyback...

I Know that you need to adjust the number of turns ont the primary depending on the voltage u use on the flyback! I just whanted to say that on the H-bridge (clasic one) you have only half of the input voltage.

ok?

[jmartis2]

That's right, but you can absolutely get the same power :)

[jmartis2]

I think they were around 20cm (8")

[jmartis2]

izidor, sorry I accidentaly removed your message. Here I repost it: "i've got a 555 driver and a fiew flybacks laying around,,, and i have one tiny from an black and white monitor like 13 inches. and the same primari winding and the same setup and this tyny one gives twice as long arcs like tne others. BUT I DON'T KNOW WHICH IS THE NEGATIVE HV PIN !!! Please help

when i bring the anode neer the pins there are 5 pins and they all give the same arc?????? WTF am i gonna do with that?

Please help me

[jmartis2]

P.S: i took it from an working mon and i've got one more."

Measure if the pins are internally connected together (by some windings). If so, it doesn't matter which one you use.

[izidor7]

Yes I'm shure that is the case. however i've got at home maybe 6 old tvos and there are some preti huge flybacs... who knows maybe i'll put some videos here... who knows!

I got to admite you are preaty insaint to play with such things. DON'T GET YOURSELF KILLED! Alvays be careful And keep up the good work. It seems like you know what you'r doing :-)

RESPECT MAN!

[izidor7]

BTW the half bridge brings HALF TNE INPUTE VOLTAGE ON THE FLYBACK! So there isn't 320VDC , but 160VDC there shure is.

The H-bridge is constructed so that you have +160V . 0V. and -160V and that is a syncron power supluy without that the H-bridge won't work

I'm considuring to use 380VAC / 120Hz and convert it to 540VDC and i would get on the H-britdge 270V and that would mean more POWER

Have fun folks!

[jmartis2]

No that won't, if you use less turns with less voltage you will get more current in the winding and that means the same power. You can have an input of 12V and 100A which is the same as 1200V and 1A.

[birutattoo]

fake!!

this is fire!

lolololol

[zanta24]

Whats the striking distance? You should make a voltage multiplier for that :)

[jmartis2]

I think it was ~4cm, not really much. DC flybacks can do a lot more.

I don't like multipliers because you only get "bangs" out of it and no flaming arcs.

[TheLightningStalker]

I've got a flyback the size of my fist and it won't do that.

[insomartin]

by now does your flyback still works? cause i don't think that would take that much punishment...

[jmartis2]

yes it does, many others have failed but this one is extra tough...

[cenzo188]

that would make a sick jacobs ladder, although the spark looked different than the ones ive seen in most ladders.

[samssoftwareuser]

hey jan, what tv is that out of? what do you think my old tv from 2002 would be like?

[jmartis2]

your TV will probably contain a rectified "diode split" transformer, these usually cannot provide such high powers like the old(er) bare wire ones. This particular one is from a B/W TV somewhere from the 70's

[SmashCOBamberg]

cool vid... i got a tv from the 70s, too, but how to get the flyback and how to poer it? please answer!!!

[jmartis2]

Build a half-bridge inverter. I will not be teaching you the basics of switching power supplies :) (google half-bridge flyback driver)

[vivdal]

I see..

A simple yet elegant approach.

[vivdal]

Great video.

What is the input voltage.

At those output voltages Im intimidated!!

[jmartis2]

the voltage is from rectified mains and fed into halfbridge.

[13377331133773311337]

lol but it makes 50hz sounds..

so it seems to be a transformer on 230VAC, -> MOT, OBIT or something like this.

[jmartis2]

It makes 50hz sound because the filter capacitor does not smooth the waveform perfectly.

[13377331133773311337]

ah, okay :D so it is "50hz moduled" :P

Ok, nice transformer anyway :-)

greetings

[pickford7812]

lol notice the lights get dimmer

[jovicakluk]

i dont think that the lights are getting dimmed from the power consumption, i think it has something to do with the camera getting saturated

[iNeedAhaircut99]

burn those curtains, they're awful
